“…Therefore, it should be considered that in some cases where hits are so severe, martensitic microstructure is not suitable [4]. The similar wear obtained with different hardnesses was probably due to different ductility, linked with different behaviours of the hard, second phase particles.…”

“…In wear resistance, both hardness and toughness play important roles; therefore a desirable microstructure should be hard enough and ductile. In some applications where hits are so severe, martensitic microstructure is not suitable in spite of its good hardness [4,5]. In some cases, bimetal casting pieces are used because of their great impact resistance [7].…”

“…The specimen were polished and then etched by Nital 3% for microstructural observations by optical and scanning electron microscopy. Since the implementation of pin on disc and pin abrasion tests may not be reliable due to their different wear mechanisms in comparison with practical SAG Mills, wear test was done in a laboratory steel jar mill, 230mm in diameter [6]. For the wear test, 20 mm×16 mm×10 mm cubic specimens were prepared.…”

Wear behaviour of austempered , pearlitic and martensitic Fe-0.7C-2.3Cr-0.4Mo-0.5Si alloy was studied and compared with high Mn austempered ductile iron. The steel was austenitized at 900°C and austempered at 320°C in salt bath for different times to obtain bainitic microstructure. The wear test was carried out in laboratory jar mill, 230 mm in diameter with iron ore as the abrasive material. Hardness test and scanning microscopy were used to characterize the microstructures and wear results. It was found out that the martensitic steel has the best wear resistance followed by the steel sample austempered for seven hours.

“…In order to control the abrasive contact conditions, it is common that wear tests are simplified to laboratory scale pin-on-disk, ball-ondisk or impact-abrasion experiments [1][2][3][4][5][6]. In most of these tests, it is clear that the contact pressures and thus the wear rates remain at a rather low level compared with the actual mining conditions.…”

“…Low-stress abrasion and high-stress abrasion are types of three-body abrasive wear. [21][22][23] In three-body abrasive wear, the terms low-stress abrasion and highstress abrasion have been distinguished primarily based on whether the applied stress is sufficient to fracture the abrasive particles. [22] When the abrasive particles fracture (high-stress abrasion), it tends to generate fresh sharp cutting edges, increasing particle angularity.…”

Two medium carbon low-alloy MnSiCrB cast steels containing different Cu contents (0.01 wt pct and 0.62 wt pct) were designed, and the effect of Cu on the mechanical properties and corrosion-abrasion wear behavior of the cast steels was studied. The results showed that the low-alloy MnSiCrB cast steels obtained excellent hardenability by a cheap alloying scheme. The microstructure of the MnSiCrB cast steels after water quenching from 1123 K (850°C) consists of lath martensite and retained austenite. After tempering at 503 K (230°C), carbides precipitated, and the hardness of the cast steels reached 51 to 52 HRC. The addition of Cu was detrimental to the ductility and impact toughness but was beneficial to the wear resistance in a corrosion-abrasion wear test. The MnSiCrB cast steel with Cu by the simple alloying scheme and heat treatment has the advantages of being high performance, low cost, and environmentally friendly. It is a potential, advanced wear-resistant cast steel for corrosion-abrasion wear conditions.
